NSC Calculator: Maturity Value & Tax Amount Calculation Explained

What Is an NSC Calculator?

How to Calculate NSC Interest Rate?

Example of Calculating Interest With the Post Office NSC Calculator


The NSC calculator works on the compound interest formula. Here, the interest is compounded annually. So, the formula to calculate the maturity amount will be:

P [1+ R/100]^n




Investment Amount (P)


Interest Rate (R)

6.8% p.a.

Lock-in Period(n)

5 years

Upon placing the respective values in the formula, we get,

Maturity Amount =₹ 100000[1+ 6.8/100]^5

                                 = ₹1,46,254

As such, the total interest earned is ₹(1,46,254 - 1,00,000) = ₹46,254.

From the above calculation, it is clear that an individual investing ₹1,00,000 will earn a total interest of ₹46,254 in 5 years, and his/her total amount upon maturity.

Thus, by using an online 5-year NSC interest calculator, individuals can quickly get these mentioned results.
